SECTION 4: SYSTEM WIRING

General Information

It is essential that this product is installed correctly, in particular with respect to a person's safety and connec-
tion to the mains electricity supply. This product is not suitable for installation, maintenance or connection by
the user. A competent, qualified engineer, with for example NACOSS approval, must carry out installation and
maintenance.

Siting

The control panel enclosure (plastic box or metal box), must be sited indoors in a secure area where it cannot
be readily interfered with. There must be adequate ventilation, ample light and easy access for servicing and
maintenance. It is not suitable for siting externally or in harsh environments where it could be subject to high
humidity, extremes of temperature, chemical atmospheres, high dust levels, or in a position where it may be
subject to being dripped on, or splashed by, water or other fluids.
The enclosure base must be securely fixed to a vertical, smooth, solid surface that is a part of the fabric of the
building. The position chosen must allow the cabinet lid to be removed and allow unhindered access for
installation and maintenance.

Ventilation

While the control panel has been designed so that no part attains an unsafe temperature it is important that
adequate ventilation is provided around the cabinet, therefore the cabinet must not be positioned close to
heat-radiating equipment or other sources of heat.

Cabling

The panel has high voltage barriers between the a.c. mains supply and the alarm wiring terminals. It is essential
that these barriers be maintained in the way the cables enter the cabinet, are routed inside the cabinet, and are
routed externally.
Additional holes must not be cut in the enclosure, rear entry points are provided for cables. Alarm system
cables must be neatly trimmed and not allowed to loop inside the cabinet.
Cables external to the cabinet must be either firmly affixed to the fabric of the building using suitable clips or
saddles, or mechanically protected in conduit or trunking. It must not be possible to put strain on the wiring
within the control cabinet by pulling on cabling external to the cabinet.
It must not be possible to push a finger or similar size object or instrument into any hole or cable entry point.

Mains Cable Type

The conductors of the mains supply cable must have a minimum cross-sectional area of 0.75 mm and the
insulating material on each conductor must be a minimum of 0.4 mm thick Polyvinyl Chloride (pvc). Flexible
cables must conform to the requirements of BS6500 and IEC Publication 227. Non-flexible electrical installa-
tion cables must conform to BS6004.
